Nutrition for Injury Prevention and Recovery: Key Tips for Athletes

A twisted ankle. A stress fracture. A hamstring pull that lingers for weeks. While injuries are sometimes blamed on bad luck, poor technique, or overtraining, there’s another important factor that often goes overlooked: what athletes eat. Daily food choices play a quiet but powerful role in building a resilient body and speeding up recovery when injuries do happen.

The good news? Eating well can help athletes stay healthy, prevent injury, and recover faster. A balanced approach to nutrition is a practical tool every athlete can use.

Fuel with Enough Calories

First things first: athletes need to eat enough. Not getting enough calories puts you at a greater risk for injury, weakens your immune system, slows growth and development, and makes it harder to get all the nutrients your body needs (1). Under-fueling can also mean less progress in training, lower energy, and slower recovery (1).

This matters even more for adolescent athletes, who burn significant energy through practices, strength training, conditioning, and competition, on top of everyday activity and growth needs.

Pro tip: encourage teen athletes to eat frequently, aiming for three balanced meals plus several snacks throughout the day.

Prioritize Protein

Alongside calories, protein is critical for injury prevention and recovery. It supplies the amino acids needed to build and repair muscle, strengthen tendons and ligaments, and support immune health (2).

How much protein do athletes need?

Needs scale with body weight, generally 1.4–2.0 g of protein per kg of body weight per day to build and maintain muscle (2). Injured athletes need even more, up to 2.5 g/kg/day, since the extra protein helps repair damaged tissue and limits muscle loss during immobilization or reduced activity (3, 4).

Timing matters too. Athletes should spread protein across the day rather than loading it into one meal, and should include protein after workouts to support muscle repair (2). A good target is about 0.3 g/kg of body weight per eating occasion, roughly 20–40 grams depending on the athlete’s size (2, 4).

Quality counts as much as quantity.

Protein is made up of 20 amino acids, 9 of which are “essential” meaning the body can’t produce them on its own, so they must come from food. Leucine is especially important for muscle building (3, 4).Dairy (milk, yogurt, cheese) and other animal proteins like chicken, eggs, seafood, beef, and pork are complete proteins, delivering all 9 essential amino acids in one source. Whey — one of the two main proteins in milk — stands out for its high concentration of leucine and fast digestion, making it especially effective for muscle growth and recovery. Most plant proteins, on the other hand, fall short of one or more essential amino acids, so athletes eating plant-based need to combine a variety of sources to cover their bases.

Build Strong Bones

Adolescence is a critical window for bone health — teens build 40–60% of their adult bone mass during these years, reaching peak bone mass in their early 20s (5). After that, the focus shifts from building bone to preventing loss (5).

Key nutrients for bone health include protein, calcium, vitamin D, vitamin K, magnesium, potassium, and phosphorus — best obtained through a varied diet of dairy, fruits, vegetables, whole grains, nuts, legumes, poultry, and fish (6). Dairy stands out here: a single cup of milk delivers 8g of complete protein, 25% DV calcium, 15% DV vitamin D, 20% DV phosphorus, and 10% DRI potassium (7).

Aim for 3+ servings of dairy daily (8). Easy ways to work it in: milk with meals, a cheese stick in a school lunch, a post-workout Greek yogurt smoothie, a yogurt-and-fruit parfait snack, cheese on a sandwich, or cottage cheese with fruit before bed.

Fight Inflammation with Food

To support recovery and reduce inflammation, athletes should include antioxidant- and anti-inflammatory-rich foods: vitamins A, C, and E, zinc, selenium, omega-3 fatty acids, flavonoids, and polyphenols (9). Good choices include berries, tart cherries, pomegranates, leafy greens, avocado, broccoli, walnuts, almonds, chia and flax seeds, fatty fish like salmon and sardines, and olive oil, turmeric, ginger, and garlic.

It’s best to focus on getting nutrients from whole foods instead of relying on high-dose supplements. In fact, some research suggests that taking large amounts of antioxidants like vitamins C and E might actually get in the way of your body’s ability to adapt and get stronger from training (9).

Pro tip: For an anti-inflammatory snack, try the National Dairy Council’s Berry Nutritious Acai Bowl, which combines acai, blueberries, kale, kefir, and yogurt.

Don’t Skip Sleep

Sleep is just as important as diet for injury prevention and recovery. Athletes who chronically sleep 7 hours or less per night face a 1.7 times greater risk of musculoskeletal injury (10). Poor sleep raises inflammatory markers like C-reactive protein and interleukin-6, and disrupts the growth hormone and cortisol secretion needed for muscle repair (11) — while also weakening immune function and increasing susceptibility to illness (12).

Sleep and nutrition are closely linked: sleep-deprived athletes tend to make worse food choices, often falling short on the carbs and protein needed for recovery (11).

How much sleep is enough? Despite its importance, many adolescent athletes don’t get enough, especially on school nights (13). The American Academy of Sleep Medicine recommends (14, 15):

Ages 6–12: 9–12 hours
Ages 13–18: 8–10 hours
Adults: 7+ hours

Good sleep habits to build (16, 17):

Keep a consistent sleep/wake schedule
Keep the bedroom cool, dark, and quiet
Build a relaxing bedtime routine (deep breathing, mindfulness, reading, journaling)
Avoid caffeine in the late afternoon and evening
Limit evening screen time (blue-light blocking glasses can help with homework on devices)

The Bottom Line

At the end of the day, supporting an athlete’s health and performance is about sticking to a few basics: eat enough, focus on quality protein, build strong bones with nutrient-rich foods like dairy, fight inflammation with real foods, and make sleep a priority. These habits lay the groundwork for staying healthy and playing your best.
